Raman spectra of impact zircons in the Jarva-varaka layered massif (the Monchegorsk ore region, the Kola Peninsula) [PDF]
Vestnik MGTU, 2017 Zircon crystals from granophyre norites of the Jarva-varaka massif of the Monchegorsk ore region (the Kola Peninsula) have been studied by means of back-scattered electron (BSE) imaging and Raman spectroscopy.

Variscan sourcing of Westphalian (Pennsylvanian) sandstones in the Canobie Coalfield, UK [PDF]
, 2010 The zircon age spectrum in a sample from the Canonbie Bridge Sandstone Formation (Asturian) of southern Scotland contains two main peaks. One is Early Carboniferous in age (348– 318 Ma), and corresponds to the age of igneous activity during the ...

Does Zircon Shape Retain Petrogenetic Information?
Geochemistry, Geophysics, Geosystems, 2023 Zircon shape is commonly reported during geochronology and geochemistry analyses of igneous, metamorphic, and sedimentary rocks, but the relationship of zircon shape to primary growth environmental conditions remains poorly constrained.

Improvement of the Thermal Stability of Zircon by Formation of the Solid Solution of Cr in Zircon
Journal of Asian Ceramic Societies, 2020 In this paper, the effects of Cr2O3 additive on the thermal stability and zircon decomposition were investigated. The substitution of Cr at zircon lattice and the formation of solid solution were also discussed. Cr2O3 was added at up to 4 wt.% to zircon.

The effect of low-temperature annealing on discordance of U–Pb zircon ages
Scientific Reports, 2021 Discordant U–Pb data of zircon are commonly attributed to Pb loss from domains with variable degree of radiation damage that resulted from α-decay of U and Th, which often complicates the correct age interpretation of the sample.

Extensional faulting on Tinos island, Aegean sea, Greece: How many detachments? [PDF]
, 2007 Zircon and apatite fission track (ZFT and AFT) and (U-Th)/He, 40Ar/39Ar hornblende, and U-Pb zircon ages from the granites of Tinos Island in the Aegean Sea, Greece, suggest, together with published ZFT data, that there are three extensional detachments ...

An X-ray diffraction method for determining the amount of xenotime in a zircon sample [PDF]
Bulletin of the Geological Society of Finland, 1984 An X-ray method was developed for determining the amount of xenotime or zircon in a zircon ‒ xenotime sample. Such analyses are useful in establishing whether a solid solution exists between xenotime and zircon or whether there is a separate xenotime ...
